The spread

0.11× estimated

These two figures may not measure the same thing

At 0.11×, the Medicare figure is 0.2 times what pharmacies pay or less. A gap that large means the two figures may not describe the same unit or product, or the price may have changed between their dates; check what each one covers before relying on the multiple.

Part D averages every strength and form sold under “Carbidopa-Levodopa ER” / “Carbidopa/Levodopa” into one figure, so it is not specific to this NDC.
